Design and Performance Analysis of DWDM-PON

Abstract

This paper presents on the design and analysis of Dense Wavelength Division Multiplexing Passive Optical Network (DWDM-PON) which is the upcoming trend technology nowadays to transmit up to 40 Gbps data. Various modulation techniques such as Non-Return Zero (NRZ), Return-Zero (RZ) and duo binary coding are simulated in this DWDM-PON. Using OptiSystem software, DWDM-PON is designed and simulated for 32 channels with spacing of 100 GHz and bit rate of 10 Gbps. An Erbium Doped Fiber Amplifier (EDFA) and Dispersion - Compensating Fiber (DCF) is deployed in the DWDM design. It is found that duo binary modulation technique gives the best performance with minimum BER of 2.66x10-19. From the simulation result, it also found that the proposed DWDM PON design is suitable to be deployed for current network.

Characteristics Analysis of Hybrid Optical Amplifier with Doped Fiber Variations for Fiber Optic Communications Network

“…Because of the higher need for data transmission over extensive areas, a system network of optical fiber requires comprehensive bandwidth gain and good performance to handle the burden of a sufficient network at long distances. The technology that can be used to optimize the bandwidth gain on the network fiber optical is Erbium Doped Fiber Amplifier (EDFA) implementation [7]. The optical amplifier applies by doping the core of singlemode optical fiber with Erbium atoms to strengthen the optical signal [8].…”
